  • some or all of the wireless mobile devices 902 - 910 can send a summary failure data message, such as by SMS, either automatically or user initiated. Although only a fraction of the devices with faults may send such a summary, these reports can create an alert regarding a problem in the fielded devices.

In some applications, a higher penetration can be desirable and achieved through repeated broadcasts.
